My invention is a friction hinge adapted for use on doors windows or the like to retain such doors windows. etc in adjiiist'ed position and to a low i'iillaction as a hinge when de "ed.

of my invention hingc which will itllOWll, door; window or the like to rein n in any adjusted position due to the ii i ion of the creel elements oi the hinge one on the olil i. I

A more particular ohjiec t o'l lllYli'lVQ-HtiOll is to make a hinge which allows one/part to he squeezed slightly t Allie/l and thereior develop a clamping it'i-iction between the squeezahle part of the hinge kind another rigid elci'nent. 'lhns a feature oil iny inveu tion is in allowing a she squeezing to-- ge'tl'ieii' of one o? the hii'ige elements in the direction or the pintle thiis securely clan'iping one of the hinge elcn'ien'ls tothe other. I

ll further object elf my invention in a hinge structure to util ze washers or the like oi suitable v. ringii'iaterial surroundino; the pintle between adjacent i'ia ts (iii the hinge and one or the parts oi? he hinge he adopted to ,he srweezed tolherehy illLflL the friction insistence at thewasher so that the hinge will remain in any desired position. v i

In constructing my :lriction hinge 1 form one dine hinge elements with a solid hnh thro gh wh' huh being ri secured to the hingelead, Ti lie other hing n1. her is lJlOVliilPil with a ,phii'i'ility of? huhsol ear type to liton the cndsoit the rigid huh. 'llhe lezi'l to which the car hnhs are connected is formed with a slit or the like so that the leaf may he slightly squeezed. "tenet-liar thereby pressing the ears tightly against the solid huh. This squeez ing action done by the pintle which e:-:- tends through the ear hubs and the solid huhs the pintle having screw threads to allow tightening-and thereby clamping the leaf elements of the hinge in adjusted posicorporating wearing washers between the rigid huh and the ear huhs so that the wear resis'tence olt' friction is on the washers, This allows hinges to be made of i'naterial which the pintlc l'ilifiTCTZ'tOIKl; the

is not adapted to frictionw] wear and to have I washers inserted of fr ction material.

iMy invention willhe more readily understood from the following description and which: a

side elevation of a friction hinge Fig 1 niadei 'i' accordance with my invention.

2 is an elevation similar to Fig. 1 showing longitudinal section through the huhs of the l i 2 the leaf 1 having a central hub 3 idly secured, thereto; the leaf 2 having the huh 3., The body portion of the leaf 2 'l'or 'ned w th aslot 6' and if desired with d out enlarge out portion '1 this latter givin ogr esiliency as hereunder set forth.

The le i. 11s usually formed with a slot 8 and with acut-out section 9 similar to the slot'and cut-ontsections 6 and 7; these heing more or less ornamental and to balance "thelunge n design. lt will he noted that the leaf 1 has a substantial. strip ofmetal 10 ad acent the hub; However, the hub forms a sufiicient coiinection between thetwo sec tions the leai. The leaf 3 has an upper section 11 and, a lower scction'lfl which are connected.

pair [of *ashers 13 are fitted between 2 id huh S'and the ear hlihs 4 and 5. li'he e washers are shown more in detail in Fig. 3 and comprise a Hat annulusl l with a rimlfi; the rim having a cut-out segment l6: such segment being adapted to fit on each side oi the upper and lower parts 17 and 18 o l the leaf 1. I

The pintle 19 preferably has a straight shank 20 with a screw threaded end 21; the head 22 of the pintle being of any suitable design and having a nut 23 with finger grips 2 anda screw driver keri' 2% or the like to allow tightening. The head 22 and the nut 23 are preferably of similar design.

In the construction of the hinge of Figs.

'1 and 2, the leaves 1 and 2 and their're'speo hiihs -12 and?) to register in alinement with swing freely.

' nut 23 the leaf 2 is slightly squeezed together iron or other material which may not form a good friction or wearing surface. Therefore the washers 13 may be made of bronze, brass or other goodfriction material to give a resistence to the action of the hinge.

The manner of use of the hinge is substantially as follows:

It will be understood'that the hinge will be secured to doors, windows or the like in the ordinary manner and by having the nut 23 loose on the pintle the article hinged may However, on tightening the onaccount of-the slot 6 and the cut-out section 7 allowing the ears 4: and to squeeze slightly towards each other; therefore bringing in a compression'resistence on the washers 13. It will be manifest that suflicient resistence may be developed by tightening the pintle to hold heavy doors and windows in adjusted position.

In the construction of Fig. at, the washers 13 are omitted and the leaf 2 is shown with an integral ornamental extension 25 on the ear hub 5. The pintle 26 has a head 27 with a hole 28 extending therethrough to allow turning of the pintle with a nail or the like as a lever. The opposite end 29 of the pintle is threaded and engages threads 30 in the hub '5. The action of this hinge is substantially the same as that of Figs. 1 and 2. hen the pintle is turned by the head 27 as it is screwed tightly in the hinge 5, it

. draws this hub and the hub 4 in close contact with the similar hub 3 and thereby develops a friction resistence between the hubs; therefore restraining the movement of its the leaves of the hinge, holding the hinged article in the desired position. This type of hinge is useful for constructions in which the material ofthe hinge is good friction material such as brass orbronze hinges or the like. I

It will be noted that in my friction hinge the web of the hinge leaves, the portion of the leaves having the apertures for securing same to the door and door jamb and the hub, are substantially in one plane. The slot6 and the cutout part 7 weaken the web, allowing the hubs 4 and 5 to be squeezed inwardly against the hub 3 of the rigid part of the hinge.

Although I have shown my hinge as of only one type, it is manifest that it may be changed materially in design to suit various types of articles to be hinged and therefore may be altered in general construction and in specific details. Such changes would be within the spirit of my invention as set forth in the description, drawings and claims.

Having described my invention, what I claim is:

1. A friction hinge comprising in combination a pair of hinge leaf elements, each leaf having a web portion, a part to be connected to a door or a door jamb and a hub portion, said various portions being substantially in one plane, one of theleaf elements having a slot in the web with hubs spaced aparton opposite sides of the slot, the other hub element being rigid and having a central hub, washers, each having a flat annular portion and a rim, the rim having a cut-out section, said washers being fitted between the connecting hubs with the cut-out. portion of the rim engaging the rigid leaf element. a pintle extending through the hubs and the washers, and a nut threaded on the pintle allowingpressing of the outer hubs and the washers against the inner hub, the leaf element having the slotbeing resilient.

2. A friction hinge comprising in combination a pair of hinge leaf elements, each leaf having a web portion, a part tobe con nected to a door or a door jamb and a hub portion, said various portions being substantially in one plane, one of the leaf elements having a slot in the web with hubs spaced apart on opposite sides of the slot, the other hub element being rigid and having a central hub, a pintle extending through the hubs, and a nut threaded on the pintle allowing pressing of the outer hubs against the inner hub, the leaf element having the slot being resilient.

In testimony whereof I have signed my name to this specification.
